IGNITION-SWITCH Lock? Applicatioiifiled 'Augn'st s, 1925. Serial N011 471501:

The purpose-of the-"invention is to pro" vide a device involving 'the principles of a permutationlock for use ii1=c0nnectioir with' the ignitioirswitches of auto vehicles, so that"- for the actuationbf theswitchyit shallbe necessary for'the 'operator to know the com"- bination; to provide a construction of this sort in which the combination may be Varie 'd,-- in the: event i thati a previous combination I secured to the instrument-board and flanged shal'lha ve become known; and to pro'videia device of this sort which is extremely simplein construction and inay,therefore,*be manufactured" cheaply andm'arketed at small=cost-.'-

Withthispurpose 'in view, the invention consists I in a 'construction 'and "combination of partsof which a preferredembodiment is illustrated the;accompanying drawings;

The'disks "10, 11 and 12, which constitute the'movable elements of thedevice; are disposed in superposed relatioii' concentrically with the shaft ljwhich passes through cen tral eyes formed in the disks, the disks'be ingspaced apart by interposed collars 15 and the uppermost disk'be-ing actu'able by aknurled'knob 16 secured to a thimble 1 7 flanged, as at 18,"thefiange 18 being secured to'the uppermostdisk 10. The knob'16 is also connectedto the shaft orspindle- 14; pin 19 passing diametrically through agdepending flange on the knob; through the sleeveand through theshaft.

The several disks 10, 11 and :12 are of panshape with their upstanding flanges 20' concentrically arrangedgso that their peripheral flanges Ql may lie in "a' common plane; The top; face of each peripheral fiange'is inscribed with thenumbers'l'to '8, inclusive,

The lighting switch 3% while smaller, is idehti! cal in constructionwith the ignition switch) an'd'is carried in a su'pple'mental casing 85 identical with the casings or housings of th e ignition switch and "the dished The supple-- mental casing ififi, w-liile carried-by the remov able bottom 27, is disposed to onesi'de of the housing 'or' casi-ng' of'tli'e' di'sks; so, that'- 38 interposed between the flange 18 and. the inner face of the instrument-board, and the spring 87 bearing upon the end of the shaft interposes frictional resistance sutficient to prevent its too free turning.

The disks 1.0, 11 and 12 are each provided with threaded openings or eyes 39 angularly spaced according to the spacing of the digits on. their peripheral flanges but these eyes are all at uniform radial distances from the shaft so that, in certain positions of the various disks, the eyes are in registration, and

normally all those eyes except those desired for use are plugged, as by screws 40. The plan for plugging all but one or for plugging several in each disk leaves at least one open in each disk so that the several disks may be arranged with the eyes 39 in alignment with the bushing 41 in the face of the instrumentboard. In such position of the several disks, the switch operating key 42 may be inserted, the shank 43 of the latter passing through the bushing 41, through the several eyes 39 and entering the movable member 30 of the ignition switch, so that member may be actuated and the ignition circuit closed.

In the actuation of the lock, the upper or outer disk 10 is the only member actuated by the knob 16. When the number which has been selected for use to define the open or unlatching position of this disk has been selected, that number is brought under the observation opening 22 and the hole or eye 39 diametrically opposite will then be in position under or behind the bushing 41. This opening must be left open and all of the other openings or eyes 39 are preferably plugged by the insertion of the screws 40. The same method of setting applies to the remaining disks, so that when the selected three numbers are below the observation opening, there will be three unobstructed openings 39 below or behind the bushing 41, so that the actuating switch key may be inserted. When the disks have been moved so that these selected openings or eyes 39 have been disaligned, realignment may be efiected by the actuation of the knob 16.

The rotation of the knob 16 imparts rotary movement to the upper or outermost disk 10 and this motion is finaly communicated to the disk 11 when the radial pin 44 on the upstanding flange of the disk 10 engages an inwardly directed pin 45 on the corresponding flange of the disk 11. The two disks then rotate together until the pin 46 on the outside of the upstanding disk 12 engages an inwardly directed pin 47 on the flange of the disk 12. The three disks are then rotated by the knob until the first digit of the combination, as 4 in Figure 1, appears under the observation opening. Reverse movement must then be imparted to the knob 16, for further movement in the same direction would result in carrying the disk 12 around with the knob but to leave the digit 4 under the opening, the operative connection between the disks 11 and 12 must be disengaged and the reverse movement of the knob will effect this since the pin 44 will then move away from the pin 45 and when the disk 10 has completed a movement of 360 degrees, the pin 44 will engage the pin 45 on the other side and rotate the disk 11 in the opposite direction and, when the necessary digit such as 6 in Figure 1 appears below the observation opening, the rotation of the knob is reversed and the disk 12 moved in the original direction until its selected digit, such as 3 appearing in Figure 1, falls below the observation opening. The unobstructed openings or eyes are then aligned and the switch key may then be inserted and the switch actuated.

In the relocking operation, the mere rotation ofthe knob, after the withdrawal of the switch actuating key, will serve to effect the necessary disarrangement of the relation between the disks, so that they will obstruct the passage of the switch-actuating key.
